- Zinc – crucial for immunity and wound healing.
- Iron – prevents anemia by helping in red blood cell formation.
- Phosphorus and Calcium – important for bone health.
- Selenium – acts as an antioxidant mineral protecting against cell damage.
5. Phytochemicals
- Phenolic acids and flavonoids – natural compounds with anti-inflammatory and antioxidant properties.
- Lignans – plant compounds that may reduce cancer risk.
